A displacer for an engine includes a body extending along a displacer longitudinal axis from a displacer first end surface to a displacer second end surface. At least one channel extends between a first opening in the displacer first end surface and a second opening in the displacer second end surface and has sidewalls therebetween defining a channel flow path. The first opening is located at a first radial distance from the displacer longitudinal axis in a first radial direction and the second opening is located at a second radial distance from the displacer longitudinal axis in a second radial direction. At least a portion of the channel flow path has a component in an angular direction that is at an angle to both the first and second radial directions.

The utility model relates to the technical field of operation machinery, and discloses an extended-range hybrid power system and operation machinery. The extended-range hybrid power system comprises: an engine; the generator is connected with the engine; the electric drive axle is electrically connected with the generator through the first controller; the energy storage device is electrically connected with the first controller through the second controller; the operation motor is electrically connected with the second controller; and the loading operation mechanism is connected with the operation motor. When the range extending type hybrid power system is in a pure electric running mode or a pure electric operation mode, the engine does not work, and zero consumption of fuel oil is achieved; when the extended-range hybrid power system is in the extended-range running mode or the extended-range operation mode, the engine does not directly drive the vehicle to run or operate a motor, the engine does not need to change output power according to the running power requirement, the engine is always in an efficient economic area for power generation, and the engine displacement and power are smaller than those of a traditional fuel vehicle engine. Fuel consumption and tail gas emission are reduced, and energy conservation and emission reduction are achieved.
